A low battery alarm is available at register 4308. This becomes active when the battery voltage
falls below 11.3V, and clears when the battery voltage rises above 11.8V. Supply voltage is also
monitored, and an alarm is available at register 4309. This becomes active if the supply voltage
falls below 8.0V, and clears when the supply voltage rises above 9.0V.

2.4 The Host - 105G Link
For the host device, the 105G"looks" like a single device (or a "virtual PLC"), containing the I/O
for the complete wireless I/O system.
2.4.1 Modbus / DF1
The user selects whether the 105G-MD1 should act as a Modbus Master or Modbus Slave or
DF1 device.
The data type and baud rate of the serial communications must be configured at the 105G to
match the host. Data types can be 7 or 8 bit, even/odd/no parity, with 1 or 2 stop bits. Data rates
can be 300 - 19200 baud.
